Fuel Efficiency - Miles per Gallon to Kilometer per Liter

Output: Press calculate

Formula:km_per_liter = miles_per_gallon × 0.425144

Introduction to Fuel Efficiency Conversion

This tool calculates the fuel efficiency of a vehicle in kilometers per liter (km/L) given its efficiency in miles per gallon (MPG). It is useful for comparing fuel efficiency in countries that use different measurements.

Parameter usage:

Example valid values:


Data validation

The miles per gallon value must be a number and cannot be negative, reflecting real-world usage.


Converts MPG to KM/L, facilitating international fuel efficiency comparisons. The conversion factor used is 0.425144, derived from the ratio of miles to kilometers (1 mile = 1.60934 km) and liters to gallons (1 gallon = 3.78541 liters).
